 a commonly used mathematical model for electrical and computer systems circuit model the elements that comprise the circuit model ideal circuit components based on mathematical techniques and is used to predict the behavior of the circuit model and its ideal circuit components circuit analysis the actual electrical system, constructed from actual electrical components physical prototype the energy per unit charge created by the separation voltage the rate of charge flow electric current points of connection to other circuiet components terminals has only 2 terminals, described mathematically, cannot be subdivided into other elements ideal basic circuit element whenever the reference directions for the current in an element is in the direction of the reference voltage drop across the element, use a positive sign in any expression that relates the voltage to the current passive sign convention the product of the current in the element and the voltage across the element power a device that is capable of converting nonelectric energy to electric energy and vice versa electrical source a circuit element that maintains a prescribed voltage across its terminals regardless of the current flowing in those terminals ideal voltage source a circuit element that maintains a prescribed current through its terminals regardless of the voltage across those terminals ideal crrent source establishes a coltage or current in a circuit without reling on voltages or currents elsewhere in the circuit independent source establishes a voltage or current whose value depends on the value of a voltage or current elsewhere in the circuit dependent source models a device capable of generating electric energy active element models physical devices that cannot generate electric energy passive elements the capacity of materials to impede the flow of current or the flow of electric charge resistance the circuit element used to model resistance resistor v=iR v=-iR Ohm's law the recipricol of resistance conductance the algebraic sum of all the currents at any node in a circuit equals 0 Kirchhoff's Current Law a point where two or more circuit elements meet node the algebraic sum of all the voltages around any closed path in a circuit equals 0 Kirchhoff's Voltage Law when just two elements connect at a single node series
